Compilers: Principles, Techniques and Tools, known to professors, students, and developers worldwide as the Dragon Book, is available in a new edition. Every chapter has been completely revised to reflect developments in software engineering, programming languages, and computer architecture that have occurred since 1986, when the last edition published.

New chapters include: Chapter 10 Instruction-Level Parallelism Chapter 11 Optimizing for Parallelism and Locality Chapter 12 Interprocedural
